3. Nov. 8, 2000RIKEN CC-J CC-J Status Number of Users Accounts –CC-J Adimin … 7 –PHENIX-J … 28 (regional use) –PWG MC … 2 CPU usage (right figure) but, no CPU factor applied,... Regional use –DST production trial version: phs5+TOF projection –post DST analysis MC production –(2+1) x 100 K events ONLY PISA processed Problems due to PRDF writing Response and MC reconstruction chain maintenance required! CPU usage (crude counting)

4. Nov. 8, 2000RIKEN CC-J CC-J Status II 100 K MC –So far only PISA code works –Run00a and run00b finished –Second round of run00b under process With new MVD geometry –A couple of troubles Root library changed during production Root has 2x10 9 bytes limit –Split to 1000 events/run (run00b) Objectivity/DB –Dead copy of 10/2, 10/26 version worked at CC-J –New proposal: NFS version, World wide Time stamp

5. Nov. 8, 2000RIKEN CC-J New Hardware Same as S.Yokkaichi reported last September New Fiber channel RAID: –2.85TB soon, another one later New Alta Cluster and upgrade –Dual 1 GHz CPU x 16 nodes, soon. Another 16 nodes later. –Slower 450MHz (32 CPU) and smaller Disks will be replaced (933MHz, 18 GB SCSI) –ECC memory Sun E450 for another NFS server (or Data mining)

6. Nov. 8, 2000RIKEN CC-J Requests from CC-J Required to have RIKEN visitor position Send proposal for large and middle class projects All CC-J activities are subjects to report on RIKEN annual report Living cost may be supported for CC-J visitors CC-J Opening Ceremony February 16, 2001 (to be confirmed)
